Latest Patents

Yoshiharu Shigeta holds a patent for a "Digital frequency divider suitable for a frequency synthesizer." This invention includes a first or prescaling counter that selects between first and second frequency division factors in response to a first control signal. The device divides an input signal frequency based on this control signal. Additionally, a second programmable counter frequency divides the output of the first counter by a third frequency-division factor. A third programmable counter further divides the output of the first counter by a smaller fourth frequency-division factor. A switching control circuit converts the output of the third counter and supplies the converted signal back to the first counter as the first control signal. This digital frequency divider is particularly suitable for use as part of a phase-locked loop frequency synthesizer. Yoshiharu Shigeta has 1 patent to his name.
